Answer: See explanation
Step-by-step explanation:
a. how old is Cheryl?
Cheryl's age = d + 5
b. how old is Brandon?
d + 5 + 2
= d + 7
c. what was the difference in their ages 5 years ago?
Cheryl age five years ago = d
Brandon's age five years ago = d + 2
Difference = d + 2 - d = 2 years
d. what is the sum of their ages now?
Cheryl's age = d + 5
Brandon age = d + 7
Sum = d + 5 + d + 7
= 2d + 12
e. what will the sum of their ages be two years from now?
Two years from now,
Cheryl's age = d + 5 + 2 = d + 7
Brandon age = d + 7 + 2 = d + 9
Sum = d + 7 + d + 9
= 2d + 16
f. what will the difference of their ages be two years from now
Two years from now,
Cheryl's age = d + 5 + 2 = d + 7
Brandon age = d + 7 + 2 = d + 9
Difference = Brandon age - Cheryl age
= (d + 9) - (d + 7)
= 2 years.
Answer:
y = 2x - 5
Step-by-step explanation:
The slope for a parallel line is the same as the slope in the given equation. Therefore the slope of the new line will be 2 m= 2
use that slope and (2, -1) to find b
-1 = 2(2) + b
-1 = 4 + b
-5 = b
Plug m and b into y = mx + b
y = 2x - 5
The completely factored form of the Wen's polynomial, which has the four terms initial, is,
<h3>What is the factor of polynomial?</h3>
The factor of a polynomial is the terms in linear form, which are when multiplied together, give the original polynomial equation as result.
Wen is factoring the polynomial, which has four terms.
'
Take out the greatest common factor from the equation and make separate groups as,
Rearrange the above equation as,

Answer:
The answer is 3 , 1 , 2 .
Step-by-step explanation:
I will give an example.
e.g.
x² + 3x + 2
Step 3 :
Set the equation equal to zero :
x² + 3x + 2 = 0
Step 1 :
Completely factor the equation :
x² + x + 2x + 2 = 0
x(x+1) + 2(x+1) = 0
(x+2)(x+1) = 0
Step 2 :
Set each factor equal zero and then solve for the variable :
(x+2)(x+1) = 0
x + 2 = 0
x = -2
x + 1 = 0
x = -1
